Can you attach your pics?

 

[lohk]

@Andrew:
It was a bit of a work to get the new components out and running - so please be patient and let Ingo show his success. You could have helped to find the minor mistakes perhaps - with your knowledge.
Sound great, so I am reported.

 

[NRWler04]

Can you attach your pics?

Which pics should I attach? Isn'nt it better to send per email?

 

[AndrewT]

Lohk,
I can't contribute if I can't see what is being proposed.
He could attach his pics, but instead I suspect he is using a remote server/s to distribute them.

The last pic I can see is in post69.

 

[lohk]

I can see them all, so I thought you were ennoyed by the sheer amount of images. Sorry for my misunderstanding.

 

[Vostro]

I also see them all,
AndrewT, maybe install another browser, Firefox or something

 

[AndrewT]

Not my browser.
I am already using Firefox.
It's the settings of my protection/security.
If the "barred" list includes the remote server site because that site has a history of distributing "dodgy" files then the security prevents download to my PC.

This is easily solved. Attach the pics to DIYaudio.

Gentlemen,

another update: NERO Setup nearly completed .....

From left to right:

NERO SA 1 - Power Amp in double Mono Design based on Nytech CPA 602s
NERO EXO 1 - Electronic CrossOver for ARC 050
NERO PRE 24.4 - Pre Amp based on NAIM NAC 42 with 4 Power Rails - 24.5V
NERO SP 1 - Power Supply for PRE and EXO with 500VA Toroid

The setup makes quite nice noise

NERO has landed - In memoriam to Richard Hay

Gentlemen,

my NERO's are finished and ready for listening. Please see the pictures. To bad that you can't listen to them over the www.

Many many thanks to lohk from Austria and Nytecholdie from PFM for the support they gave me.

Everybody who is interested is invited for a listening session.

Best regards from Germany

Ingo
